RegEx a bit of confused

simple task but a little overkilled here

app.js
// Type inside this function
function isValidHex(text) {
  const hexRegEx = /^#[a-f 0-9]{6}$/i


}

const hex = document.getElementById("hex");
const body = document.getElementsByTagName("body")[0];

hex.addEventListener("input", e => {
  const text = e.target.value;
  const valid = isValidHex(text);
  if (valid) {
    body.style.backgroundColor = "rgb(176, 208, 168)";
  } else {
    body.style.backgroundColor = "rgb(189, 86, 86)";
  }
});

Hey Albert!

You're almost there!

You created a RegEx object called hexRegEx. All RegEx objects have a test() method. Just call the test() method, pass the text parameter, and return the boolean that the test() method returns.

return hexRegEx.test(text);

Hope that helps! Let me know if you have any more questions :)!
